Chapter 18 Multiplexed External Bus Interface (MEBIV3)
NOTE
When the system is operating in a secure mode, internal visibility is not
available (i.e., IVIS = 1 has no effect). Also, the IPIPE signals will not be
visible, regardless of operating mode. IPIPE1–IPIPE0 will display 0es if
they are enabled. In addition, the MOD bits in the MODE control register
cannot be written.
18.4.5 Low-Power Options
The MEBI does not contain any user-controlled options for reducing power consumption. The operation
of the MEBI in low-power modes is discussed in the following subsections.
18.4.5.1 Operation in Run Mode
The MEBI does not contain any options for reducing power in run mode; however, the external addresses
are conditioned to reduce power in single-chip modes. Expanded bus modes will increase power
consumption.
18.4.5.2 Operation in Wait Mode
The MEBI does not contain any options for reducing power in wait mode.
18.4.5.3 Operation in Stop Mode
The MEBI will cease to function after execution of a CPU STOP instruction.
